The ankle block is a safe and effective means of providing sensory anesthesia to the foot. The nerve supply to the foot at the level of the ankle is relatively superficial and consists of five nerve branches. The posterior tibial, which supplies the plantar aspect of the foot; the saphenous, supplying the medial portion of the foot; the deep peroneal, supplying an area between the great and sec...

The objective of this paper is to develop an analytical framework to representing the ankle-foot kinematics by modelling the foot as a rollover rocker, which cannot only be used as a generic tool for general gait simulation but also allows for case-specific modelling if required. Previously, the rollover models used in gait simulation have often been based on specific functions that have usuall...

INTRODUCTION While only 15-20% of patients with foot and ankle injuries presenting to urgent care centers have clinically significant fractures, most undergo radiography. We examined the impact of electronic point-of-care clinical decision support (CDS) on adherence to the Ottawa Ankle Rules (OAR), as well as use and yield of foot and ankle radiographs in patients with acute ankle injury. MET...

While it is generally believed that the choice of prosthetic components affects amputee gait, systematically quantifying the effects of prosthetic design on amputee walking is difficult [1]. A simulation model capable of predicting human amputee gait could allow for quantitative, systematic investigations. Existing models of amputee gait are either too complex for a predictive study (e.g. [2]) ...

Background Infectious gangrene of the foot is a serious complication of diabetes that usually leads to a certain level of lower-extremity amputation (LEA). Nevertheless, the long-term survival and factors associated with mortality in such patients have yet to be elucidated. Methods A total of 157 patients with type 2 diabetes who received treatment for infectious foot gangrene at a major diab...

Post-burn contracture and deformities of the foot and ankle joint with respect to other localizations account for 3.5-5% of cases. Functional disturbances of the foot and ankle joint affect the functioning of the entire lower joint, its statics, and the patient's gait and bearing, and can even lead to distorted pelvis, curvature of the spine, and other disturbances. Between 1990 and 2002 we tre...

A computer-controlled mechanism that fits a standard ankle-foot prosthesis was designed to capture the absorbed energy in the ankle and delay its release until specific times in the gait cycle. This mechanism used a direct current motor to take up and hold the compression of a carbon-fiber ankle joint. Based on the timing of the contact forces between the foot and the ground, a microprocessor r...

BACKGROUND AND PURPOSE This study investigated the non-velocity-related effects of a 1-bar rigid ankle-foot orthosis on the gait of hemiparetic subjects, with particular emphasis on the muscle activity of the paretic lower limb. METHODS Twenty-one hemiparetic subjects who had been using an ankle-foot orthosis for equinovarus deformity for <1 week participated. Patients walked cued by a metron...

OBJECTIVE To compare the effect of foot orthotics and rehabilitation exercises by assessing balancing ability and joint proprioception in athletes who have chronic ankle instability. METHODS Forty-one athletes who visited hospitals due to chronic ankle instability were randomly assigned to two groups. One group had ankle rehabilitation exercises while the other group had the same rehabilitati...
